Abstract: PURPOSE: A device is provided to restore symbol timing through a digital signal process by obtaining timing information with a single-sided prefilter and a multiplier in a high speed communication system. CONSTITUTION: An analog/digital conversion part(10) converts a transmission signal applied from a voltage control generator(70) to a digital signal based on a sampling clock. A single-sided prefilter pair(20) includes a low-pass prefilter(21) for pre filtering the digital signal to output low-band symbol timing information and a high-pass prefilter(22) for pre filtering the digital signal to output high-band symbol timing information. A multiplier(30) outputs symbol timing information by multiplying the signals from the pre filters(21, 22). A band-pass filter(40) filters the symbol timing information for an exact symbol frequency. A first phase detector(50) detects a symbol timing phase from the bass-pass filter(40) and outputs digitized(sampling) values with respect to a sinewave having four-times higher frequency than the symbol frequency. A loop filter(60) applies the four-times higher frequency to the analog/digital conversion part(10) as a sampling clock. A second phase detector(80) outputs a data restoration block from the digital signal applied from the analog/digital conversion part(10).
